Twenty kinds of ciguatoxic fishes such as grouper, moray eel, barracuda, catfish and snapper, etc. were collected from fish markets in Bangkok, Chanthaburi and Chonburi. Liver and meat were extracted with ether and the presence of ciguatoxin was checked by the mouse test. Ciguatoxin was not detected in any of the samples. On the other hand, water‐extracted fractions under acetic acidic conditions from meat, skin, intestine, liver and ovary of five kinds of puffer collected from Chanthaburi, Samut Sakorn and Trat caused mouse paralysis or death. The ovaries of the green rough‐backed blowfish and the starry blowfish, which are very popular in Thailand, contained large amounts of tetrodotoxin. The starry blowfish contained 1482.0 mouse units of tetrodotoxin per gram of ovary.
